Translation and Validation of Dizziness Handicap Inventory in Hindi Language

Area of Science:

• Otolaryngology
• Audiology
• Health Psychology

Background:

• The Dizziness Handicap Inventory (DHI) is essential for quantifying dizziness impact on daily life.
• Validated translations are needed for diverse linguistic groups to facilitate global research and clinical practice.
• This study addresses the need for a Hindi version of the DHI.

Purpose of the Study:

• To translate the Dizziness Handicap Inventory (DHI) into Hindi.
• To validate the Hindi translation (DHI-Hindi) for use in Hindi-speaking populations.
• To ensure the DHI-Hindi is a reliable and valid measure of dizziness impact.

Main Methods:

• Standard translation guidelines were followed for the DHI-Hindi.
• A cross-sectional study involving 153 Hindi-speaking dizziness patients at an ENT clinic.
• Reliability (Cronbach's alpha, split-half) and construct validity (factor analysis) were assessed.

Main Results:

• The DHI-Hindi demonstrated good internal consistency (Cronbach's alpha = 0.785).
• Factor analysis confirmed a three-factor structure, aligning with previous DHI studies, indicating good construct validity.
• No ceiling or floor effects were observed, suggesting a comprehensive measurement range.

Conclusions:

• The translated DHI-Hindi is a reliable and valid instrument.
• This validated tool can now be used to assess dizziness impact in the Hindi-speaking population.
• Facilitates clinical assessment and research comparisons for Hindi-speaking individuals experiencing dizziness.
